OTR/CONSTRUCTION TYRES
Michelin Reveals New Generation of RDT Tyres
cycles made daily.
Wear resistance of the X®TRA LOAD has also been increased by 8% over the X®QUARRY S due to an increased volume of rubber in the new tread design and better load distribution across the contact patch. The volume of rubber in the new range is at least 9% more than in X®QUARRY S and almost 30% more than in some of leading competitors’ tyres of the same size. Additionally, this greater volume of tread rubber in contact with the ground gives better load distribution, improved wear resistance and an increase in tyre life. Tyre endurance is also increased due to new tread patterns. MICHELIN® X®TRA LOAD PROTECT, particularly, has interlocking blocks and improved heat dissipation that reduce the temperature in the tread area by up to 12oC.
Productivity, as measured by TKPH/TPMH, quantifies productivity and is a function of load and distance covered in an hour. For, respectively, the new X®TRA LOAD GRIP and X®TRA LOAD PROTECT, the TKPH is increased by at least 20,3% and 13,8% in the A4 compound, and at least 11,7% et 41,7% for the B compound, when compared against previous Michelin ranges. This
Michelin has released what it says are the first ever ‘3 star’ 24.00R35 tyres on the market. This is a new tyre range for 40 to 80-ton payload rigid dump trucks (RDTs) with an increased load capacity, an improvement in tyre life and a big
conditions on flat, dry surfaces – where the priority is protection and damage resistance, such as quarries and construction sites.
After many years and billions of tons of materials moved, Michelin is replacing the XDT, X®Quarr y S
and X®HAUL, the reference tyres for RDTs in the tyre size – 24.00R35. The increased payload potential of the new product range is reflected in the new name – MICHELIN X®TRA LOAD. The new tyre will be available from 1 July 2017.
The new MICHELIN® X®TRA LOAD range will allow users to maximise the productivity and continuity of their operations; whatever the conditions of use. In addition
to the increased load capacity, the X®TRA LOAD range boasts an improvement in tyre life and an increase in the TKPH – so larger loads can be moved further, in the same time period. The three main areas of improvement are as follows:
Load capacity is key to all earthmoving machiner y and the new reinforced casing of the new MICHELIN® X®TRA LOAD makes it the first 24.00R35 tyre on the
market to be credited with a
‘3 star’ rating. This is the result of a design which improves stress distribution within the tyre. In practical terms, this equates to an 8% higher payload or an increase of 9 tons in load capacity per machine; a significant increase in productivity when multiplied by the number of

productivity increase through an improved TKPH/TMPH. This range comes in two variants, namely the MICHELIN® X®TRA LOAD GRIP and the MICHELIN® X®TRA LOAD PROTECT.
The former is intended for soft, loose, muddy ground conditions – as often experienced in mining and quarrying operations on slopes/inclines, where the priority is high grip and traction and the latter for hard, sharp abrasive
